Copy task add option not to copy control procedures

I would like to suggest the idea when copying a task to add a parameter whether to copy the control procedures and the program objects. Most of the time when you copy a task you don't want the control procedure of the copied task to be bound to the new task, so most of the time you need to de-assign the control procedure.
So when unchecking this parameter the copy task does only copy the task, the task parameters, the task references and the table task and table task fields. (in that case you need to create a new control procedure just like when adding a new task)
